[scripts] Added ADC calibration to setup.py.

This automatically calibrates the MMCM phase on both ADC's of a
board and optionally plots the ramp outputs.
[scripts] Changed catchdata.py to look for subscribers in /application/bin.

Previously was set to /common/bin.
[tbs_plugins/Makefile] Removed all -lrt flags for plugin linking.

These are unneccesary since tcpborphserver3 is built with rt.
[tbs_plugins/Makefile] Use ld instead of gcc for linking.

This avoids a certain error when cross-compiling.
[scripts/setupsma] Added a "swapips" option to direct-connect setup code.

This is only useful when using the direct-connect corner-turner with visibility
date not going through the switch and instead directly going into the control
computer.
[scripts/syncsma] Made syncsma consistent with sma-walsh changes in @f6feaf27

Basically the sma-walsh-arm tcpborphserver command no longer takes a Unix time
synch parameter since it gets it over DSM instead.
